Cirque Do Soleil Mystere

The first time I went to a Cirque Do Soleil show was in las Vegas when I was 7 yrs old with my mom. And I thought it was absolutely amazing! Now some years later, I look back at tht specific show Mystere, which is a permanent show in Treasure Island in Las Vegas, and I think about how are the performers and musicians able to perform or play with the same feeling or enthusiasm, if they play this same show twice or 3 times everyday for many years... It must be really tiring to do the same act or play the same song for many years. you have any thoughts about how they deal with this? my thoughts are that they have every scene, movement, or note so memorized, that it just becomes a natural thing and part of the job. They loose the feeling and emotion, and become almost mechanical and specific. like matt mentioned the other day in class. If an actor writes at the end of every line in a script the thoughts and actions of that specific line, then you can play a scene as many times as you want, the same exact way.
